"Don't use your tongue to wipe your nose."

We have some friends whose youngest has the same impressive yet equally icky ability as my oldest to touch her nose with her tongue. While this trait can sometimes, somehow, come in handy, it mostly works best in "Hey, look what I can do!" situations. But I guess that really depends on who is doing it and who is watching. Anyway, apparently aforementioned sweetie pie had a runny nose the other day and our dad friend happened to look over at the exact moment of her using her tongue to, well, clean things up. He calmly made the above statement, then simply followed it up with another straightforward directive: "Go get a tissue." And that was that.
